Hey i actually just dealt with this problem last week ona friends car. the oil in the center with the spark plugs is because you need a new valve gasket. not a cover unless its cracked just the gasket and it costs about 25 dollars at your local parts store. its very easy to install and a quick fix but try to get all the oil out of the center as you can and rub a little bit of old oil on the gasket before you install it. it helps stop dry rot. try this first and then see if the backfiring and stalling stops. if not, you may need to change your spark plugs again even if you already have because chances are the oil thats already in the hole has burned up the spark plug. so give your spark plugs a good check while you change your valve gasket.

SOURCE: runs in park, put in gear drives a bit, then stalls

If you have a twelve pin connector for test, (just to the right of the column under the dash)you can jump from the second terminal (going right to left) on the top row, and ground. ck eng light will flash codes.
Personally from what you have said, i'd lean towards either coil, fuel pump.or filter. See if you can pull codes...

SOURCE: Spark plug drenched in motor oil

If it is oil, the oil is leaking into the cyliinder past the piston ring. You need to have this checked by a mechanic orherwise you will have a more expensive problem.

you need to check the fuel pressure,and did you mean you replaced the distributor or just the rotor because inside the distributor is a pickup plate that some times causes this also 02 sensor can cause your check engine light on if so go to chain auto parts store they usually read your codes for free.

Why does it run well, then backfire and stall?

make, model, year? backfires are spontaneous burning (exploding) of unburnt fuel outside of the combustion chamber. suspect bad spark plug/s, ignition coils, ignition timing, computer, leaking fuel injector, etc. scan for trouble codes, then post back. because the problem is intermittent, problem manifests only when hot (engine at operating temperature) do tests for both cold & hot conditions. test resistances (ohm) of suspected sensors: cam & crankshaft position sensors, ignition coils (if possible),(search the web for the recommended procedures). also test voltages at the computer (search the web for the pin outs of the computer of your car). also check associated relays (like for the fuel pump, etc.) a bad relay may have its coil open when heated, then becomes good again when cold. i suspect the car may have a good fuel delivery but the sparks are not coming in on demand, thus backfiring.

Chevy venture stalled

Compression, spark , timing , fuel for any engine to run. Don't forget a stopped up catalytic convertor will have the same effect as you described. Backfiring of course is fouled plugs, bad plug wires, look for arcing from wires when it is dark outside. If it has a distributor check for cracked cap, had my 91 GMC start backfiring then die due to ignition module inside distributor going bad. It would start back up after it cooled for about 10 minutes.

Backfires and stumbles when gas pedal is floored

There are a lot of diffferent things possible, the backfiring is usually caused by a timing issue. Which could also cause some of your loss of power, but not always. Try checking your fuel pressure to see if there is a clog, also your timing is computer controlled so this means your timing chain is worn spark plugs and wires could be bad or you have a cracked distributor cap rotor bug bad, or even a bad distributor or even as simple as wrong ground placement for motor. Best choice is to start small and then work your way up. Also if disributor has ever been taken out then you will have to reset your oil pump drive because your distributor runs your oil pump with your cam-shaft.

Engine turns over but wont start? it has spark! and fuel!

Pull out # 1 spark plug and put back into plug wire, rest on motor block so that end of electrode is against metal. turn motor over and have a finger or compression gauge in # 1 cylinder, check to see if spark occur at same time as compression (compression will blow air past finger or raise gauge). When you say it has fuel do you mean gas tank has fuel? Are you sure fuel is getting to the cylinders? are plugs wet with fuel? Does it turn over but kinda thumps or backfire (Caugh)? Check the spark and compression first. if they don't happen at same time, the timing skipped or belt broke. if all is good pull plugs and inspect, could be flooded (WET) from fuel. either replace or spray with starting fluid and compressed air to dry them. spray starting fluid into air intake if starts then stalls, try again, if same thing happens then you have a fuel problem. try these suggestions first 1/2 hr time table, hopefully sucess, if not it sure indicates fuel.

I went through water and stalled engine and have got new speark plugs, wires for them, new distributator cap and rotor. their is no water in oil or in the air intake. what could be probablem. it happened...

you may need to change your fuel filter sounds like you have water in the line. you can put some gas treatment or octane booster in the tank. but make sure that the new wires are in the right sequence for the firing order.

Backfires in manifold on motor on acceleration. runs ok low speeds

Spark plug wires. If you take it in a garage or wait till it's dark, and have somebody brake torque it while you watch, you'll see spark jumping. But don't get run over! Do it in reverse. Or just change the wires.

Will start up run for awhile then stall and wont restart

Hello, I would start with a general tune up. Spark plugs and wires, Fuel Filter, Oil Change and Filter Change, Air Filter Change, Some injector cleaner would not hurt eirther. Be sure to lubricate your high mileage car and also use a farily good oil for your motor as well. The run for awhile problem sounds like bad spark plugs. I would change your spark plugs, wires, distributor cap, and rotarty button.

Car stalls while driving at high speeds

i would start by checking the spark plugs and leads. if that ok i would think there is a problem with the dispack that the spark plug leads fit to, if its cracked or any rust i would replace.
